Editing Windshield (section)

==Disposal==
[[Waste disposal]] of [[laminated glass]] is no longer permitted in a landfill in most European countries as the [[End of Life Vehicles Directive]] (ELV) is implemented. A study<ref>{{cite web |url= http://www.surrey.ac.uk/CHAMP/documents/pilk.pdf|title= Laminated Car Windscreen Recycling|author=<!--Staff writer, no author credit--> |archive-url= https://web.archive.org/web/20081031083149/http://www.surrey.ac.uk/CHAMP/documents/pilk.pdf|archive-date= 2008-10-31|url-status= dead}}</ref> by [[Surrey University]] and [[Pilkington Glass]] proposes that waste laminated glass be placed into a separating device such as a rolling mill where the glass is fragmented and the larger [[cullet]] is mechanically detached from the inner film. The application of heat then melts the laminating plastic, usually, [[polyvinyl butyral]] "PVB" enabling both the glass and the interior film to be recycled. The PVB recycling process is a simple procedure of melting and reshaping it.
One possible method of recycling of simple automotive laminated windshields could involve heating the windshield to above the melting point of the PVB interlayer and then separating the glass plies. This depends chiefly on the differential melting points of PVB and glass and is not suitable for other interlayer materials such as silicone based materials.
